My favourite Australian TV show is one called "Insight", it's made up of a small panel of guests plus the audience. There's a great host and she involves everyone in the show. Each time, they have a subject and it's basically hashed out with her moderating/encouraging/etc conversation.
Here's a good recent one on racism, followed by the link where you can see ones about fear of Islam, arranged marriages, Iran, Pakistan, etc.

Sometimes the show frustrates me because the moderator does allow everyone to have their say and sometimes you don't want to hear certain things. But what can you do :)
